Application filed June 22, 1925. Serial No. 38,753.

This invention relates to gas generators of the type employed in the manufacture oit gas from oil7 and an object of the invention is to provide a construction that will eliminate to a hi tion ot soot .and carbon.

Another object is to provide iorf economical generation of the gas;

Another object is to properly distribute the. heat to all parts ofthe gas generator chamber.

Another object is to obtain the proper gas-making temperature inthe upper zone where the gas-making nozzles are loca-ted, without the necessity `of overheating lower zones where combustion is effected.

A further object isA to prevent vertical motion of the products of combustion in the combustion 'chamber'.Y

A still further object is to provide a` 'construction that will' not deteriora-te rapidly and tha-tis oi Va nature that will permit of use tor comparatively large units. y

' Other objects and advantages will appear hereinafter. y

' The accompanyingl drawings illustrate the invention: Y

Referring to :the drawings, the generator comprises vertical yside walls 5 having flat innerftaces and preferably Aarranged in vthe form ot av polygon having more'than Vfour sides. lnptliis instance there alresiX walls to produce a hexagon. generator is domelshaped4 and the vbase yis 'l indicated at 7.

are indicated Aat 8, there being two in the presentinstance and the rooifs of said coni-A each being bustion chambers are` arcuate, formed of a series of spaced arches 9. The laterally by spreaders 10 which also function to keepl the arches properly spaced so as tofprovide vertical passages 11 The arches-are flat on their upper taces as indicated at 12 and supportedon sai( ilat positioned suitable oil burners 25 Thetop 6 ofthe. loil used' The combustion chambers` i'ied `to any desired' loc-ation.

between `adjacent arches,

'iaces are checkerbrick 13 which partially lill the gas generating chamber le to a level indicated at 15. Above the level 15,*the gas generating chambei' is unobstructed and below said level is'A provided in its side walls with ports 16 at intervals -aroundthe circumference of said chamber.' The ports 16 open into van annular vertical passage 17 that is formed in the ,walls 5 and that extends to thev upper tace of the varchesr 9. The passage 17 vcommunicates at its lower end with the vertical inter-arch passages 1l and at its upper end with the vacant space above thechecker-brick. Y

IThe ,top 6A is provided with a vent 18V which may be closed by aclosure19.` The closure 19 is hingedatQ() or otherwise movably mounted.

'i Extending through the walls of the un obstructednpper portion of the chamber '14 `are oil inlet make nozzles 2l which need i not be described andv illustrated in detail as their constructionis well understood in the4 art relating to' .gas generation. The term make nozzles isemployed in the art and in thisy specification lto designate the nozzles bywhich vthe oil and steam'that malte the gas are admitted to the gas generating chamber.

The `combustion chambers 8 are provided V*with clean-out openings Q2 which may be closed by doors 23 of any suitablec'onstruction.

Opening ftrirough some of the walls 5 are ports 2li, eachy combustion chamber being provided witha pair of ports, oi each pair are positioned diametrically opposite to each other as clearly shown in Fig. 2 ot the drawings. In these ports are which preferablyemploy an air. blast and steam tor effective atomization and burning of the 'in'heating the 'generator.`

Communicating with both combustion chambers 8 is a gas off-take 26 to which is and thev ports connected the pipe, not shown1 whereby the oil gas manufactured in the generator is car- .The port 26 is ,positioned at the .junction oi' the two combustionv chambers and thus serves to take the combustible oil gastrom both of them.

Y To operate the gas generator burners setinto operation. The burners Y s n described '.above, the closure 19 will belopened andthe ilol Ying, and consequentJ port more or less, or until the temperature of the walls of the combustion chamber is about 22000 Fahrenheit. lt will be noted that because of the burnersot each set being diametrically opposed, the blasts from said burners meet mid-way the combustion chambers, thus de'f'lecting the blasts so that they will not tend to strike the walls 5. Also itV will be noted that any of the burningV gases that strike the walls 5 will be deflected radially inward` toward the more central portions ot the combustion chambers, thus protecting the walls 5 from overheatrapid deterioration of said walls. Some of the 'flaming gases that reach the walls 5 will direce'ily upwardly through the passage 17 into the unobstructed space above the checlerbriclr so that the zone in which the gas-making nozzles are located will be quickly heated to almostas high a temperature as that obtained in the combustion chambers. it the temperature is approximately 2200O F. in the combustion chambers, the temperature in the upperI portion of the chamber l-l will be approximately 2100O F.

i large portion ot the burning gases passes upwardly through the inter-arch spaces and through the checlterbricl, thus heating the chcclrerbrick. lt will be noted that some of the gases of combustion will pass from the passage 17 through the ports lG into the upper side portions of the checkerbrielr, t-hus heating` such portions to as great a temperature as is obtained elsewhere in the checkerbrick. This prevents the formation ot soot and carbon at those portions of the chcckerhrick that, without such provision tor bringing some of the heat directly from the combustion chambers thereto, would remain at a much lower temperature than the lower and more central portions of the checherbriclr.

latter thev propel' temperature has been obtained,` the luirners will be shut down and the closure 19 will be closed. Then the oil inlet nozzles 2l will be put into operation to furnish a suitable mixture ot oil and steam, from which mixture the gas is evolved by die temperature within the checkerbriclf. The oil and steam mixture passes downwardly through the heated checkerbriclr and through the inter-arch spaces and the resulting gas draw otl through the 2G. The iis-making operation will thirty minutes, more or be continued for less, or until the temperature falls below that resti and, atter a short interval of time, the` able for the gas-making operation, and
